Cinema 4D Tutorial – C4D Physical Render – Tutorial Part Two
This tutorial is the second part of a two part tutorial that Tim recently completed for 3D Artist magazine. If you would like to follow the first part where we set up a soft body dynamics simulation,
then you’ll need to grab a copy of the magazine, issue 59. I’m sure that the first part will be available online in the future but for now you will have to purchase the magazine.
First part is now online here – http://luxx.tv/3dblowup
The second part however is FREE! If you don’t follow the first part then do not worry as you can download the scene file with the dynamics baked and then use this as your starting point for part two.
In this tutorial Tim explores some of the new features of Cinema 4D Release 15, specifically working with global illumination using QMC and Light Mapping which is a fantastic combination. However there is a lot more than using GI in this tutorial. At one hour in duration you are sure to pick up some handy tips along the way.
We first generate some simple UVs so the texture sticks as the model deforms, then we build a material using a combination of shaders including sub-surface scattering, lumas, fresnel, layer shader and gradients. Sub-surface scattering shader can be quite daunting, Tim shows you how to choose the most appropriate settings for your scene and some tips for optimising the shader to speed up your renders.
Tim shows you how to convert a probe HDRI into a more suitable format for C4D so that we can light our scene with a sky object for image based lighting. To compliment the GI, we will use an Area Light and explore some of the parameters essential for controlling Area Shadows.
The tutorial uses the Physical Renderer in Cinema 4D and Tim shows you how to grapple with the parameters so you have speedy previews whilst setting up your scene. We make use of the Physical Depth of Field, adjusting our physical camera to fine tune the result.
Of course, rendering with area shadows, depth of field and sub-surface scattering will heat your CPU somewhat, so Tim renders with the new Team Render in Cinema 4D to spread the load across several machines.
In the tutorial Tim used an HDR image that isn’t included in the download due to copyright, but it is a free HDRI, so you can go download it yourself from here.
